I have. See my previous post.
Behe's response was essentially, "I know you are, but what am I?"
ID is little more than a list of proposed problems for evolution. As jennyp pointed out, even William Dembski points out that ID is still not ready for inclusion in a grade-school curriculum, and has yet to develop a research program.
If a designer plopped down the first organism on Planet Earth, wished it well, and sent it on it's way, very few people would be able to refute you. If, however, you then claimed that the designer stuck around fiddling with the genome for the next billion years, you'd be hard-pressed to make a case. Are genetic changes induced by a designer fundamentally different than changes arising from natural causes? If so, how would we go about identifying some?
